What would be your guess with a new custom gun? I have taken it out of the stock & everything works good but I have not found where release is binding against the stock. 2nd question, If you had never seen a McMillin stock how would you know if it was or not? BTW I don't use WD-40 on anything other than bolts & nuts.
Is it a stock remington trigger or an aftermarket trigger?
Jewell's have a habit of binding if the stock isn't relieved, they're wider than the factory trigger and the bolt release linkage touches the stock if the stock isn't relieved. It's an easy fix.
If it works out of the stock but binds when you put it in the stock then it's rubbing. Figure out where it's at sand a little bit of the stock.
